Cell Structure and Energy Concepts

A double membrane called the nuclear envelope.

Long DNA molecules and associated proteins form fibers in the nucleus.

Carry out protein synthesis in the cytosol and membranes.

A double membrane that separates the nucleus from the cytoplasm.

Long DNA molecules and associated proteins form fibers in the nucleus.

Carry out protein synthesis in the cytosol and membranes.

Consists of nuclear envelope, ER, Golgi apparatus, lysosomes, and vacuoles.

Dispatched to the Golgi apparatus.

Produces lipids and helps in liver detoxification.

Break down organic matter such as proteins, polysaccharides, fats, and nucleic acids.

The capacity to 'do work' or cause change.

Energy that a non-moving object may have due to its position or structure.

Due to its location and structure.

Energy cannot be created or destroyed, only transformed.

A measure of disorder, randomness, or the loss of unusable energy.

When energy is converted, entropy increases.

Enzyme that converts sucrose to glucose and fructose.

A substrate impostor that plugs the active site of an enzyme.

The head of a phospholipid that is attracted to water.

The tails of phospholipids that repel water.

Passive diffusion of molecules using proteins as facilitators.

Passive diffusion of water across a selectively permeable membrane.

Solution is the same concentration inside and outside of a cell.

Movement of molecules against a concentration gradient using ATP.

Movement of materials out of a cell using membranes.

Stomach secreting pepsin.

Movement of materials into cells by vesicle engulfment.

Phagocytosis: cell engulfs particle into a food vacuole.
